SWITCH-OPERATING M ECHANISM.

` SPECIFICATION forming part of Letters Patent No.- 738,606, dated September 8, 1903.

' l Application led February 18, 1903. Serial No. 143,966. (No model.)

ToctZZ whom ama/y concern: A

Be it knownthat we, BERTRAM J. DELzErr and WILLIAMMJ. SAKER, citizens of the United States, residin g at Philadelphia, in the county Vof Philadelphia and State of Pennsylvania,

have invented new and useful Improvements in Switch-Operating Mechanism, of which the i following is a specification.

This invention relates to new and useful improvements in switch-operating mechanism for use upon cars; and its Objectis to provide la simple and inexpensive device which may and these `rails are adapted tobe moved from or toward the track by `means of suitable mechanism located upon the car and in control of the person operating the car. The

`shifting rails are adapted whenlowered to come into contact with arms connected to and extending upward from the tongueof a switch and swing said tonguelaterally upon its fulcrum and hold it in such position until the truck of the car has passed thereover.

The invention also consists in the further novel construction and combination of parts hereinafterlmore fully described and claimed and illustratedin the accompanying drawings, showing` the preferred form of our invention, and in which- Figure l is a plan view ofA a car-truck in shifting mechanism connected thereto. Fig. 2 is a side elevation of a car having our improved attachment thereon. Fig. 3 is a detail view of the shifting device detached, and Fig. 4 is a plan view of double trucks of a car and showing the means for operating the shifting rails upon the trucks in unison.

` Referring to the figures by numerals of reference, 1 is thetongue of a switch, and to the inner face thereof adjacent to its freeend is bolted or otherwise secured an arm 2, having an upwardly-extending lng 3. This arm projects from the tongue at an angle thereto. The tongue is held normally in position against the adjacent rail of the track by means of a coiled spring 4, the outer end of which abuts against a stationary block 5 or any other suitable device for preventing displacement of the spring.

The means for operating the tongue is located upon the truck 6 of a car and comprises brackets 7, secured to and extending inwardly from opposite sides of the truck and having vertical arms 8 slidably mounted therein. The arms Sateach side of the truck are connected toashifting rail 9, the ends 10 of which extend outward at angles. The upper ends of each pair of arms 8 are connected by a stripll, and preferably coiled springs 12 are arranged on the arms and interposed between this strip.

and the bracket 7. A shaft 13 is journaled lin hangers 14, depending from the bottom of the car, and is provided at its ends with cranks 15, which are connectedby means of links 16 to the centers of the strips 11, before referred to.

and is connected by means ofv a rod 18 to a piston 19,-slidably mounted'withina cylinder 20,: which is suitably secured to the bottom of the car. A pipe 21 extends from one lend of the cylinder and is connected to a pipe 22, projecting from one end to the other of` the car and communicating with tanks 23 for holdingl compressed air. Al valve 24 is 1ocated within the pipe 22, adjacent to each tank 23 at a point within easy reach of the operator upon the car.

When a car approaches the switch. and it is desired to shift the tongue so as to permit said car to travel upon the siding, oneof the valves 24 is turned so as to admit the compressed air into cylinder 20 by way of pipes 22 and 21. Piston 19 will be promptly forced longitudinally within cylinder 20 and cause arms 17 to swing and partly revolve shaft 13.l This movement of the shaft will force the strips 11, arms 8, and shifting rails 9 downward, and at the same time springs 12 will be compressed. When the rails Qare in lowered position, one of them is adapted upon vapproaching the switch to contact with the lug 3, connected to the tongue 1, and said lug and tongue will be forced laterally by the inclined end of said rail and will be held in such position until said rail passes the lug, at

An arm 17 is secured to the shaft 13 and extends downward therefrom ICO f pipe 22 into the cylinder 26.

which time the spring 4, which has been compassed the valve 24 is closed, and said valve' may be so constructed as to act as an exhaust for the air which has been forced into the cylinder 20 and pipes 21 and 22. As soon as the air passes from these portions of the apparatus the springs l2 will return the rails 9 and the parts connected thereto `to normal position.

When two trucks-are arranged upon one car, each of them will be provided whith shifting rails, such as hereinbefore described, and in order that both pairs of rails maybe operated in unison we connect the arms 17 of the two shafts 13 by means of the rod 25, which extends through a cylinder 26 and has a pist0n 27 connected thereto and slidably mounted within said cylinder. A pipe 28 is provided for conducting compressed air from the It will be obvious that when air is admitted to the cylinder both pairs of shifting rails will be operated in unison during the longitudinal movement of the rod 25, connected to piston 27.

We do notwish to limit ourselves to the use of compressed air for operating the mechanism herein described, as any other suitable power maybe employed in lieu thereof.

In the foregoing description we have shown the preferred form of our invention; but we do notlimit ourselves thereto, as we are aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and we therefore reserve the right to make such changes as'fairly fall within the scope of our invention.

Having thus described the invention, what is claimed as new is- 1. The combination with a truck having brackets secured to and extending inward from the sides thereof; of a pair of arms mounted within each bracket, a rail secured to each pair of arms and having outwardlyextending ends, strips connecting the arms of each pair, a rotary shaft, cranks upon the shaft, links con nectin g said cranks and strips, and means for rotating the shaft whereby the arms and the rails connected thereto are moved downward from the truck.

2. The combination with a truck having brackets secured to and extendingv inward from the sides thereof; ofapairof arms slidably mounted within each bracket, a rail connecting the lower ends of each pair of arms and having outwardly-extending ends, a strip `'retrace ys connecting the upper ends of each pair of rarms,'springs upon the arms and interposed between the brackets and strips, a transversely-extending shaft, cranks at the ends thereof, and a link connection between said cranks and strips whereby downward movement may be imparted to the rails from the shaft.

3. The combination with a truck having inwardlyextending brackets secured to the sides thereof; of a pair of vertical arms slidably mounted Within each of the brackets, a shifting rail connecting thelower ends of each pair of arms and having outwardly-extending ends, a strip connecting the upper ends of each pair of arms, springs upon the arms and interposed between the brackets and strips, a revoluble shaft, cranks at the ends thereof, link connections between said cranks and the strips, an arm upon the shaft, and means for vpartly rotating said arm and shaft whereby downward motion may be imparted tothe Shifting rails.

et. The combination with a truck having inwardly-extending brackets secured to the sides thereof; of a pair of vertical arms slidably mounted within each of the brackets, a shifting rail connecting the lower ends of each 'pair of arms and having outwardly-extending ends, a strip connecting the upper ends of each pair of arms, springs upon the arms and interposed between the brackets and strips, a revoluble shaft, cranks at the ends thereof, link connections between said cranks and the strips, an arm upon the shafts, a cylinder, a tank, a .valved connection between said tank and cylinder, a piston within the cylinder, and a rod connecting said piston and the arm of the shaft.

5. The combination with a spring-pressed switch, and a tongue having an upwardly-extending lug connected thereto; of operating .mechanism comprising brackets, vertical arms slidably mounted within the brackets, shifting rails connected to the arms and having outwardly-extending ends adapted to be brought into contact with the lug, strips connecting the arms, springs upon the arms and interposed between the brackets and strips, a shaft, cranks at the ends thereof, links connecting said cranks and the strips, a tank, a cylinder, a valved connection between said tank and cylinder, a piston Within the cylinder, a rod extending therefrom, and an arm upon the shaft connected to the rod.

In testimony whereof we affix our signatures in presence of two witnesses.
